Principle of work of the present utility model is such:
Detected wheel shaft 19 is positioned on the wedge energy disperser 15 between the front and back wheel shaft spring locator card 33 after entering base 5 along propelling track 39.Wheel shaft on the roller support 17 has received the signal that detected wheel shaft 19 puts in place to level sensor 38 at this moment, energy disperser oil cylinder 14 starts the top shoe that drives wedge energy disperser 15 and retreats decline, the wheel rim slowly land that makes detected wheel shaft 19 can not cause the impact to wheel rim roller bearing 16 and roller support 17 on wheel rim roller bearing 16.Center centering oil cylinder 12 rises then, makes the wheel that places on the crossbeam 1 directly measure weight 21 and places the centralized positioning weight 8 on the left and right column 2,37 to descend simultaneously.When wheel footpath is measured the wheel of weight 21 and detected wheel shaft 19 directly the summit is contacted, being contained in the weight of wheel footpath measuring in the weight 21 receives corresponding signal and makes the wheel footpath measure weight 21 to stop to descend, also stop at 1/2nd places that wheel is directly measured weight 21 dropping distances in this weight of centralized positioning simultaneously 8 to level sensor 40.Then vertical lift oil cylinder 13 is being with end face probe oil cylinder 10 to rise to and centralized positioning weight 8 contacted positions, weights in the centralized positioning weight 8 receive corresponding signal and make vertical lift oil cylinder 13 stop to rise to level sensor 40, this moment end face pop one's head in 11 center just in time with the centrally aligned of detected wheel shaft 19.
After end face was popped one's head in 11 centering centers, the cavity piston bar 52 of end face probe oil cylinder 10 stretched out and makes the end face probe 11 that is connected on the end face probe spline rod 56 be close to the end face of detected wheel shaft 19.Owing in the cavity piston bar 52 compression spring 53 is housed, end face probe 11 is an Elastic Contact with the end face of detected wheel shaft 19, both guaranteed that end face probe 11 can not be damaged by pressure, guaranteed again that end face probe 11 is close to detected wheel shaft 19 end faces of rotation all the time, can not slip up flaw detection.In this simultaneously, axle body probe oil cylinder 23 and axle journal probe oil cylinder 7 also drop on the position of the axle body of detected wheel shaft 19 and the required detection of axle journal with axle body axle journal probe 9.Because axle body axle journal probe 9 is to be suspended in the cavity piston bar 66 by probe card body 72 parts such as grade on the axle body probe spline rod 70,9 of axle body axle journal probes are subjected to the gravity pressure of parts such as axle body probe spline rod 70 and probe card body 72, so axle body axle journal probe 9 can not be damaged by pressure.
After the probe at above-mentioned each position puts in place, crank connecting link actuating device 6 on the crossbeam 1 begins to start, force in axle body probe oil cylinder 23 and axle journal probe oil cylinder 7 by mobile pull bar 61, oil cylinder driving lever 31, make in the chute guide rail 62 of oil cylinder dolly 30 on crossbeam 1 of axle body probe oil cylinder 23 and axle journal probe oil cylinder 7 and move back and forth, thereby axle body axle journal probe 9 axle body and axle journals at detected wheel shaft 19 are moved back and forth, and stroke that it moves back and forth and speed can be set as required.In this simultaneously, the roller bearing oil motor 18 on the base 5 begins to start, and drives detected wheel shaft 19 and rotates on wheel rim roller bearing 16, and the speed of its rotation can be set as required.
After probe detection reaches the time of setting, roller bearing oil motor 18 and crank connecting link actuating device 6 quit work, end face probe oil cylinder 10 is being with end face probe 11 to retreat, vertical lift oil cylinder 13 descends and resets, axle body probe oil cylinder 23 and axle journal probe oil cylinder 7 also are being with axle body axle journal probe 9 withdrawal original positions, energy disperser oil cylinder 14 drives the top shoe rising of wedge energy disperser 15 simultaneously, makes it to flush with the propelling track 39 of detected wheel shaft 19.After end face probe 11 falls back on the position fully, horizontally-guided bar 47 on the end face probe oil cylinder 10 touches oil cylinder to level sensor 46, oil cylinder sends to level sensor 46 and retreats the signal that puts in place, this moment the push boat oil cylinder 35 picking-up push boat bar 34 that just rises, make detected wheel shaft 19 leave board, thereby finish a task program.
